CARBONATING APPARATUS.

s mmetries forming part of Letters Patent No. 676,408, dated June is,1901.

Application filed November 5, 1900. Serial No- 355471. (No model.)

To all ruhoin it may concern:

Be it known that I, CHARLES L. BASTIAN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and usefulCarbonating Apparatus, of which the followingis a specification.

My invention relates to certain new and useful improvements incarbonating appararatus'; and its object is to provide means forautomatically regulating the supply of liquid to be carbonated, so thatagiven quantity of carbonated liquid may be constantly maintained, andfor efiecting such regulations by starting and stopping the machineautomatically as occasion requires and applying the power to the machinewhen starting it in gradual steps until the maximum desired is reached.

The invention is particularly adapted to carbonating apparatus operatedby an electric motor, one type of which forms the subject ofmyapplication filed April 9,1900, Serial No. 12,145; and this inventionhas for its especial object to apply the electric current in such a waythat the motor is always started slowly and its speed gradually andautomatically increased until the maximum is reached, and' a furtherobject is to provide means controlled and operated by the supply ofcarbonated liquid for starting the electric motor and associated meansoperated by the motor itself for gradually increasing the currentapplied thereto.

My invention has other ends in view, which will appear in connectionwith the detailed description thereof with reference to the accompanyingdrawings, in which- Figure l is afront elevation of an apparatusembodying my invention. Fig. 2 illustrates a modified construction ofthe devices for gradually increasing the current to the motor. Fig. 3 isa top View of the apparatus shown in Fig. 1. Fig. i is a detailsectional. view of the parts carried by the shaft d.

Referring to the drawings,in which like letters of reference denotecorresponding parts in all of the figures, A designates a mixing-tank,-which may be of any form and character and provided with a water-inletpipe a, a disch argepipe a, and a gas-pipe b, and B is a pump operatedby an electric motor 0, both of which may be mounted on the mixer in themanner shown. Power is communicated from the motor by means of a pinion0, carried by the motor-shaft c and meshing with a gear-wheel B on theshaft 01, which is by suitable intermediate mechanism adapted to operatethe pump. The shaft 61 also carries a sprocketwheel d, and asprocket-chain E is trained around this sprocket and a sprocket e on theshaft c,carrying an agitator within the mixer. The foregoing parts of myimproved'apparatus may be varied in construction and ar rangementwithoutdeparting from the spirit and scope of the invention, which consists,essentially, in means for automatically turning on the current to themotor and in applying the current gradually by regular steps. Abalance-lever F is pivotally secured on the mixer, and it carries aweightfat one end and a balance-tank G at its other end, which tank isconnected with the mixer by flexible pipes 9, so that the liquid willvrise to the same level in the tank as in the mixer. A switch device H isfastened on the side of the tank or in some other convenient locationand operated by means of a shifting-rod h, connected with thebalance-lever, so that when the supply of carbonated liquid becomesdiminished and the weight f rocks the lever and raises the balance-tankthe shifting-rod will be operated to throw the switch and close theelectric circuit I and in this way cause the motor to start inoperation.

It is not necessary to go into a detail description of the switchdevice, as I may employ any device of this character which can beoperated in the manner set forth and accomplish the usual result.

If the full current is turned oninstantly upon the closing of thecircuit, the pump and agitator will be started up at once at full speedand in a manner which is very liable to injure the motor and the otherparts of the apparatus. I have therefore provided an elec tric starterJ, which is suitably mounted on arms j, adjacent to the motor or in anyother desired position and connected in the circuit I with the switchand the motor. This starter may be of any preferred construction now ingeneral use and provided with any number of stops or divisions K,formingcontact-points.

In order to move the lever L of the starter pivoted at I from thelow-current step M up to the maximum step m, where it is held by themagnet N as long as the electric current is closed, I provide devices onor connected with the shaft (1, the preferred form of which isillustrated in Figs. 3 and 4, so that the initial and comparatively slowmovement of themotor-shaft, imparted thereto by reason of current willbe turned on, and at which point it is held by the magnet until thecircuit is broken, whereupon the lever is returned to 7 its pivot.

its normal position by means of a spring at (Not shown.)

I extend the shaft d beyond the sprocket d and mount thereon a governorO, which comprises .an adjustable collar 0, secured to the shaft, thearms P, pivoted to the collar and carrying ball-weights p at their outerends, andlinks Q, connected with the arms P and a movable collar R onthe shaft. .A spring r is arranged to bear against the movable collar Rand an adjustable stop 1", arranged on the shaft between the fixedcollar 0 and said movable collar. This is a suitable and simple form ofgovernor for the purpose; but I do. not restrict myself to the exactconstruction thereof, as it will be apparent to those skilled in the artthat other forms may be used with good results.

The sprocket d is provided with an enlarged hub S, constitutinga fixedstop, and between this hub and the movable collar R of the governor Iarrange a spool 'l, which is loosely mounted on the shaft (1, but partof the time held-in frictional contact with the hub S and the movablecollar R by the spring a", so that it will revolve with the shaft d,Fig. 4. A cord vU is connected at oneend to the spool T, preferably inthe circular groove 6, and to the end of aspring V, which is connectedwith the free endof the lever L, Fig. 1, the cord, however,extendingloosely through the spring and being fastened to the free end ofthelever.

The arrangement ofthe several parts is such that when the switch isoperated to close the'circuit the motor will be started at a low speed,because the. lever L of the starter is then on the low-current step Mand against the stop W, and as the power is communicated from the motorto the shaft 01 and'the latter is revolved first at a low speed thespool T will revolve also with the shaft, beingheld frictionallybetween. the collar R. and the hub S. Asthe spool revolves the cord Uwill be wound up thereon and in this way move the lever L successivelyover the several steps of the starter until it reaches the last step m,where it is held by the magnet N, and at which time the full electriccurrent will be turned on; The shaft d will then be revolving at suchspeed as to cause the governor to move thecollar R away from the spool,and

then the'spool will be loose on the shaft,

whereupon the spring V will draw on the cord to revolve the spool in thereverse di rection and unwind thecord. If the governor fails to releasethe spool at the proper time, the springV will be extended until theslack of the cord therein is'taken up, and the cord being then taut fromthe lever to the spool will cause the spool to slip on the shaft untilthe springV returns it to unwound position, as before described. I thusprovide in my improved apparatus an automatic device for graduallyincreasing the amount of current to the motor, which is thrown intooperation by the initial movement of the motor-shaft, and the full forceor any desired amount of current can be turned on and main* tained untilthe circuit is broken by automatic devices controlled by'the liquid inthe mixer. Theshaft d'operates the pump, and

in this way the liquid supplied to the mixer is regulated and is turnedon gradually until the maximum flow is attained.

In Fig. 2 I have illustrated a different con nection between the starterand the shaft for accomplishing the same result, in which the shaft 61is provided with a pulley X, and another pulley Y is arranged on thepivot of the lever L, a belt Z being trained over these pulleys. v thepulley Y, so that when the shaft d and the pulleyXthereon have causedthe pulley Y to revolve far enough to carry the lever L up to the laststep m the belt may then slip on the pulley X; but other means may becom ployed for limiting the movement of the belt,- or it may be adjustedwith such a degree of fineness thatin some cases it may slip on bothpulleys. l

I am aware that changes in the form and The belt is preferably fastenedto arrangement of differentparts of my im--- proved apparatus maybe madewithout dc parting from the spirit or sacrificing the advantagesthereof, and it will also beapparcut that I may combine the essentiallynovel features of this apparatus with different kinds of the olderfeatures, such as the mixer and pump, and I would therefore have itunderstood that I reserve the right to make all-such changes andcombinations as'fallwithin the .spirit and scope of the invention.

The spool T is provided with a flange s to retain the cord in placethereon, and in order to increase the frictional contact between thespool and the hub S, I may remove the flange Iio or move it farther upon the spool and then hollow out the hub and turn down the end of thespool to lit in the hub, or vice versa,

so that a frictional engagement will be provided on the sides as well ason the face.
